g This invention relates to adevice for assembling clothespins of the typehaving spring 'presscd movable jaws; I I An object of the'invention is the provision of a device for periodically placing pairs of clamping jaws of a spring; clothes pin in position for the application of the torsion spring to the-jaws,each completely assembled clothes pin: beingauto1natically and periodisally-replaced by a pairof jaws after the torsion spring hasbeen fitted on said jaws.

-Another object of'th'e invention is the provision of a device-for assembling the elements of a clothes pin cf the type havingspring f pressed clamping jaws and includesa-magw ine for. feeding pairs ofthe clamping jaws by gravity 'to a space wheretheyare forced by a plunger to an operative position beneath a spring holding member for the application of the torsion spring, the torsion spring beingfed while at thesame time spreading the arms and forcing the spring in proper position on a pair of the clamping jaws, the operation being continuous so that the device will function as. long as the clamping jaws are fed to the magazine and the springs are supplied to the die for application to the jaws. Afurther object'of the invention is the provision of a device forapplying torsion springs to'pairsof jaws to form a clamping element,,and in which thefeeding device for the. clamping jaws isoperated periodically and alternately with a mechanism for forcing v the torsion springs into operative relation with pairs ofthe clampingjaws, the completedjelement being. ejected periodically by the nextpair of clamping jaws; I y

This inven tion'will be best understood from a consideration of thefollowing detailedde scription in 'connefction with. the accompanying drawings; nevertheless, it is to be understood that the invention isno't confined to the disclosure-being susceptible; of such changes and modifications as shall define no material constructing the clothes'pin according to the principles of my invention, Figure 2 is a longitudinal side View of the device, D

Referring more particularly to Fig. 17, clothes pin or clamping element is shown in assembled relation and is. a type of clothes may be ejected from the magazine by means .ofthe plunger 100 and-unde'r a spring mem- 4 spring. 101 is secured toa block 101* carried by the table .35. It will be noted-that the plate 99.. is supportedin the blocksi'99. carried by the table 35. I

, A reciprocating rod 110 ismounted in bearings 111 secured to the table 35. A coil spring 112on the rod 110 engages ashoulder 1 13 and the bearings 111 tending to move the 7 rod and likewise a roller. 114into engagement with the cam member 115. The plunger 100 is secured to. theirod 110 and is operated thereby. i I V Thecam member 115is secured to the shaft cured to the circular portion 116 and the cam member 117,-fso that after, the cam portion 117 rides over the 'roller' 114 the roller will then be moved outwardly by the spring 112 as it rolls over theslidingface 119ofthe member 118. Thestraightpportion ofthe member 118 permits the roller to move the plunger '101] rapidly from the magazine P011 2 which has been resting a series of pairs of clamping arms 20'and .21, whereby another pairof clamping arms, will be disposed in alignment with the plunger 100 and also in alignment with the opening 98.

" 2. The. operation of my device is as-follows:-

' The magazine 95 is secured in the proper manner with pairs of the clamping arms 20 and 21, with the plunger 100 in the position shown in Fig. 10. The magazine curved bar '31 6,6 is supplied with the torsion springs67 and the clothes pin assembling machine is ready for operation. Thepulley 38, is revolved causing rotation of the shaft 37 and cam 115 for causingreciprocation of therod 110 therev reciprocating the plunger 100. Beciproca.

tion of this plunger forces a pair of the clampingarms 20 an d 21from the magazine 95 and under the spring. 101, which has suflicient force to retain the clamping members inv p:

; .sitionprepa'ratory to the application of the torsion spring. After the pairof arms have,

been moved into position beneath the spring 101, the fork, 62.which*has received a torsion spring 67 whichhas been removed by the fork =2. 60, forces said springbeneath theplate74 and "into engagement with rthe knife edges 82. and 86 ofthe dies 81 and.85, respectively."

As the iforkforces the torsion springfor- V wardly, the bridging portion-27. of the tor-. sionspring is in engagement with the fork 88. The bridging portion, however, moves between the knife edges 82 and 86 of the dies 81 and. 85 and therefore, rides between the under face of the die 85 and the upper face of the, die 81. The thickened outer end 81 and 85*, respectively, in the dies 81 and 85 aid in spreading the arms 28 in opposite directions and likewise the members 29 of the spring, when as shown more particularly'in Fig. 7, the member 29 of the spring 67passes beyond the thickened portions 81 and 85 which will ,slip over the, outer ends 24 of the clamping arms and 21.. The continuedlongitudinal .movement of the fork 62 be tweenthe dies-81 and 85 forces the bridging member 27 between the finger pieces 24 ofthe clamping arms 20 and 21 until the said bridgingportion is received within the transverse grooves 26. At this time, however, the members 30 of the spring 24 are riding over the outer faces of the clamping arms 20 and 21 and fit Within the grooves 30 at the same time that the bridging portion 27 is seated within the cooperating grooves 26. By this last operation the clamp or clothes pin is completely assembled and is ready to be ejected from its position beneath the spring holding member101. c 7 I While the fork 62 is being moved outwardly for applying the torsion spring to the clamping arms 20 and 21, the fork isbeing moved forwardly and engaging another torsion spring 67 and forcing it from the free end of the magazine bar 66. This spring member is then deposited on the flange 61 when the bar 50 is withdrawmfrom beneath the magazine 95. The continued rotation of the pulley 38 causes the link 44'to reverse the movement of the bar 50 sothat as has been explained, said bar moves rearwardly carrying the flange 61 rearwardly until the fork 62 passes beyond the spring member 67 whence the bridging or bight portion of said spring member is received by the fork 62.

While the bar 50 is being moved rearwardly and away from the dies 81 and 85 the cam member 117 will have been moved toa position where it will engage the roller 114 and force the rod and plunger 100 against a pairv of the clamping arms 20 and 21, thereby forcing said clamping arms from the magazine and into engagement with the completed clothespin, shown inFig. 8. The plunger 100 is moved sufliciently beyond the magazine 95 to cause. the clamping arms20 and 21 of the released pair to force the assembled H cldt'hes pin froio beneaththe spfil g 101,
